@JsonProperty アノテーション付きプロパティのみをシリアル化するように Spring の ObjectMapper をカスタマイズする方法

public class MyCustomObjectMapper extends ObjectMapper {
    public MyCustomObjectMapper() {
        super();
        setVisibilityChecker(getSerializationConfig()
                .getDefaultVisibilityChecker()
                .withCreatorVisibility(JsonAutoDetect.Visibility.NONE)
                .withFieldVisibility(JsonAutoDetect.Visibility.NONE)
                .withGetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withIsGetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withSetterVisibility(JsonAutoDetect.Visibility.DEFAULT));
    }
}
